class EMDoublePairProduction : public Module 

Electron double pair production of photons with background photons.

This module simulates electron double pair production of photons with background photons for several photon fields. The secondary electrons from this interaction are optionally created (default = false). The module limits the propagation step size to a fraction of the mean free path (default = 0.1). Thinning is available. A thinning of 0 means that all particles are tracked. For the maximum thinning of 1, only a few representative particles are added to the list of secondaries. Note that for thinning>0 the output must contain the column “weights”, which should be included in the post-processing.

Public Functions

EMDoublePairProduction(ref_ptr<PhotonField> photonField, bool haveElectrons = false, double thinning = 0, double limit = 0.1)

Constructor

Parameters:

photonField – target photon field
haveElectrons – if true, add secondary electrons as candidates
thinning – weighted sampling of secondaries (0: all particles are tracked; 1: maximum thinning)
limit – step size limit as fraction of mean free path
